*Another version of the step-down. This one is a little harder. To make this a little harder, try raising the leg parallel to the ground.

*Make sure they are only tapping their toe on the ground and not fully standing on the ground when coming back up. The point of this is to isolate the 1 leg and fire up the glutes/hamstrings. If it's impossible for them to do the tap, it's okay for them to put whole foot on the ground and stand back up on the box.

*Can be with a kettlebell or dumbbell. Kettlebell can also be held upside down.
